Trimerostephanos coarctatus
Taxonomy
Trimerostephanos coarctatus was named by Ameghino (1901) [Simpson (1967: 144) considered MACN 10965A and MACN 10966A as syntypes]. Its type specimen is MACN 10965, MACN 10966; two lots of various specimens and is a 3D body fossil. Its type locality is Mustersan of Patagonia, which is in a Mustersan terrestrial horizon in Argentina.
It was recombined as Trimerostephanus coarctatus by Ameghino (1901); it was recombined as Acoelohyrax coarctatus by Simpson (1967); it was recombined as Puelia coarctatus by Bond and López (1993).
It was recombined as Trimerostephanus coarctatus by Ameghino (1901); it was recombined as Acoelohyrax coarctatus by Simpson (1967); it was recombined as Puelia coarctatus by Bond and López (1993).

|---|---|---|
| M. Bond and G. M. López 1993 | As for comparing the Mustersian species tentatively placed by Simpson, 1967 within the genus Acoelohyrax, they were considered by Odreman Rivas (1978: 35) as representatives of the family Notohippidae, although different and more generalized than Eomorphippus. Indeed, the comparison between these species and Puelia plicata with the unpublished material mentioned above (Pampahippus gen. nov.) allows us to recognize Puelia plicata Roth, 1902 as a primitive Notohippidae and including in this genus, as a new combination, the species P. coarctatus Ameghino, 1901 and P. sigma Ameghino, 1901. Trimerostephanos coalitus Ameghino, 1901 is considered a probable large Notohippidae, very different and more advanced than the species recognized for the genus Puelia. |
